Seafoam in old Harley

[Shovel Head Ted]

I have an old Harley (shovel head) of coarse. These motors are known for carbon build up from poor combustion. Although it runs great it seems to ping more than it should, and I was thinking of Seafoaming it. Anyone ever try anything like this?
How did it work?

I seafoamed my suzuki last month. Easy and did not smoke as much as I would have thought.
